1. Autolite Platinum Spark Plugs 16-Pack for Ram 1500 5.7L HEMI V8
🌟 Key Features That Stand Out
- ✓ Necked-Down Center Electrode: Fires quicker and cleaner for better engine starts.
- ✓ Platinum-to-Platinum Firing: Offers superior durability compared to standard copper plugs.
- ✓ Yttrium Enhanced Ground: Provides excellent heat transfer for consistent performance.
- ✓ Nickel Alloy Side Electrode: Maintains a precise gap and resists erosion over time.

💡 Why We Recommend It
The Autolite Platinum series is a fantastic middle-ground for Ram owners who want more than a basic plug but do not want to spend a fortune on high-end racing components. These plugs are designed to handle the heat of the 5.7L Hemi easily. The platinum construction ensures that your spark gap stays consistent for thousands of miles, which is vital for maintaining that smooth V8 idle.
We really like that these help with cold starts. If you live in a colder climate, you will notice the engine turns over just a bit faster and more reliably. They are a direct factory replacement, so there is no guesswork involved during the installation process.

NGK is world-renowned for their spark plug technology, and the Iridium IX line is specifically engineered for enthusiasts. The extremely fine tip allows for a more concentrated spark, which means your engine burns fuel more efficiently.
These plugs are especially good if you use your Ram for towing or heavy hauling. The Iridium construction resists wear much better than platinum or copper, so you will not have to change them as often. They come in original packaging, ensuring you get the genuine quality your Hemi deserves.

This Dragon Fire Performance kit is the best value because it essentially replaces your entire ignition system in one go. By upgrading both the coils and the plugs, you ensure that the extra energy from the coils is efficiently transferred to the iridium plugs.
This kit is a favorite for truck owners who have noticed a drop in performance or recurring “Check Engine” lights related to misfires. The “Dragon Fire” name isn’t just for show—these components are built to handle heat and provide a consistent spark even under the heavy load of a hemi engine.

⚖️ Pros and Cons
✅ Pros

They offer the benefits of iridium—which include better fuel efficiency and smoother idling—at a price that is much easier to digest. These are perfect if you are planning to sell the truck soon or just need to get it through an inspection without dropping hundreds of dollars.
Despite the lower price, they are surprisingly well-made. They come pre-gapped, which is a massive time-saver when you have 16 plugs to swap out. We also appreciate the responsive customer service, which adds a layer of confidence to the purchase.
🎯 Best For
This product is ideal for: beginners and DIYers on a tight budget who need a complete set of iridium plugs for a quick maintenance job.
⚖️ Pros and Cons
✅ Pros

🌟 Key Features That Stand Out
- ✓ Reduced Emissions: Helps the engine run cleaner and more efficiently.
- ✓ Sharper Spark Focus: Minimizes misfires by concentrating the electrical charge.
- ✓ Damage-Tolerant Ground: Built to minimize spark gap growth over its lifespan.
- ✓ High Ignitability: Ensures faster combustion for a more powerful feel.
- ✓ Genuine NGK Parts: Authentic components from the world leader in spark technology.
💡 Why We Recommend It
This specific NGK 16-pack is the “go-to” choice for truck owners who put their vehicles through heavy use. Whether you are driving long distances on the highway every day or using your Ram as a work truck on construction sites, these plugs provide the reliability you need. The focus here is on consistent combustion—meaning every drop of fuel is used as efficiently as possible.
What sets these apart is their ability to resist “gap growth.” Over time, the electrical arc can wear away the metal on cheaper plugs, making the gap larger and causing the engine to work harder. These Iridium IX plugs hold their gap setting much longer, ensuring your 2014 Ram maintains peak performance for the long haul.

This product is ideal for: high-mileage drivers and work truck owners who need maximum engine reliability.
⚖️ Pros and Cons

- Genuine parts that match factory specs perfectly
❌ Cons
💬 What Customers Say

Complete Buying Guide for Best Spark Plugs For 2014 Ram 1500 Hemi
Essential Factors We Consider
When looking for the best spark plugs for your Hemi, the most important thing is the material. Iridium is the current king because it has an incredibly high melting point and can withstand the intense heat of the V8 cylinders. Platinum is a great middle-ground that offers better life than copper without the high cost of Iridium. You also need to ensure you are buying a 16-pack. Many people forget that the Hemi uses two plugs per cylinder. Buying a kit specifically designed for the 5.7L engine saves you the headache of being halfway through the job only to realize you are short eight plugs.
Budget Planning
A full tune-up for a Ram 1500 can range from $50 for budget plugs to over $300 if you include performance ignition coils. If you are doing the work yourself, you can afford to spend a bit more on high-quality NGK or Autolite plugs because you are saving on labor costs. Remember that spending an extra $50 now for Iridium plugs can save you money in the long run by improving your gas mileage and lasting twice as long as cheaper alternatives.
Final Thoughts
Changing the spark plugs in a 2014 Ram 1500 is a rite of passage for many truck owners. It is a slightly long job because of the 16 plugs, but it is one of the most rewarding maintenance tasks you can do. By picking a high-quality set from our list, you are ensuring your truck stays on the road, hauls your trailers safely, and keeps that classic Hemi power alive for years to come.
Frequently Asked Questions
Q: How many spark plugs does a 2014 Ram 1500 Hemi need?
A: The 5.7L Hemi V8 requires 16 spark plugs. There are two plugs for every cylinder to ensure more complete combustion and reduced emissions.
Q: How often should I change the spark plugs in my Hemi?
A: For the 2014 model, the manufacturer typically recommends a change every 100,000 miles if you are using Iridium plugs. However, if you notice a rough idle or poor fuel economy, it is a good idea to check them sooner.
Q: Can I use copper spark plugs in my Ram 1500?
A: You can, but it is not recommended for long-term use. Copper plugs have a very short lifespan (usually 30,000 miles) and the Hemi runs hot, which can wear them out even faster. Platinum or Iridium is a much better choice.
Q: Are the spark plugs pre-gapped?
A: Most modern plugs come pre-gapped, but they can sometimes get bumped during shipping. It is always a smart move to double-check the gap with a simple gauge before you thread them into your engine.
